Good to Know about BIOS

If updating Windows couldn't solve the error, you will need to change UEFI and TPM settings on BIOS. Thus, you need to know how to enter BIOS and how to use it.

• In order to enter BIOS, restart your PC and press the BIOS entering key on your keyboard before Windows starts.

• BIOS keys vary by computer. For example, I use Lenovo ThinkPad E595, and my BIOS key is Enter, then F2. I also have a Dell Inspiron laptop, and its BIOS key is F2.

• If you don't know what your BIOS key is, you can find it by searching on Google with the keywod like "Lenovo ThinkPad E595 BIOS key".

• The BIOS interface is different from the Windows interface. Use the Right and Left arrow keys to move between tabs, and Up and Down arrow keys between the options in a current tab. To change a value of an option, you need to enter in it by pressing Enter.

• You might see the instructions of BIOS the bottom of your screen. Notice them.

Updating the Current Windows

1. Your current Windows need to be up-to-date to be able to run Windows 11. In order to ensure this, open Start Menu and type "Update".

2. You'll see Check for Updates option, then click on it.
   

3. Even if you see "Your Windows up-to-date" message, click on Check for updates button and wait for new available updates.

4. Windows Update tool will find the available updates and install them. After the installation is finished, you'll see a message like the image below. Click Restart now.
   

5. If you see some additional updates like the image below, Download and install them by clicking that link, too.
   

6. If restart is required, restart your computer again.

7. Try again the PC Health Check tool for Windows 11.

Enabling TPM on BIOS

1. Before start, we can check whether TPM is enabled or not. To do this, press Windows + R keys on your keyboard and open Windows Run window. Then, type "tpm.msc" without quotes, press Enter.
   

2. If you see the message "The TPM is ready for use." under the Status section, the problem is not related to TPM. You can skip to the next solution method. Otherwise, you need to enable it on BIOS.
   

3. Restart your PC and press the BIOS enter key on your keyboard before Windows starting.

4. After entering BIOS, go to the Security tab by using Right and Left arrow keys.

5. Now, go to the TPM option by using Up and Down arrow keys.

6. Press Enter on the TPM option and select Enabled.

7. Save the changes by pressing the save and exit key on your keyboard. Generally the save and exit key is F10.

8. Try again the PC Health Check tool.

Enabling UEFI and Secure Boot

1. Before start, we'll check if our BIOS Mode is UEFI or not. To do this, open Start Menu and type msinfo directly. You'll see System Information in the search results, click on it.
   

2. Check if the BIOS mode is UEFI or not. If it is, you don't need to do anything related to UEFI. If not, follow the next steps and enable UEFI mode.
   

3. Restart your PC and enter BIOS by pressing the BIOS key of your PC as I explained the Good to Know about BIOS section above.

4. Go to Boot tab by using Left and Right arrow keys. Then, by using the Down arrow key go to UEFI/BIOS Boot Mode, press Enter. Switch to UEFI from Legacy by using Up and Down arrow keys, and press Enter.
   

5. Press the Save and Exit key on your keyboard and exit from BIOS. For example, F10 is the Save and Exit key for my PC. Most BIOS versions use F10 for the same purpose.

6. Your PC will be restarted, press the BIOS key again and enter BIOS. Go to Boot tab and enable Secure Boot. Some BIOS versions have Fast Boot option meaning it is not secure boot. So, you need to disable Fast Boot to be able to enable Secure Boot.

7. Start your PC and try again the PC Health Check tool.
